Yui couldn't help grinning as the last shot of the five-attack chain struck home. Death's armor flew out in all directions as a veritable explosion of energy consumed the target's body. There was no way he was getting up after-
She glanced down at her wrist. "No way."
The point-counting bracer, which had remained attached to her even after her transformation, hadn't increased its total at all. Meaning-
Smoke and flame cleared, and a very banged-up but otherwise intact Death strode out. His armor had been shattered, leaving his entire torso free- and revealing that within, he was completely empty save for a rope of blue flame connecting the base of his skull to his gauntlet, and presumably through there to his sword, which shimmered faintly with the same energy. "No freaking way," Yui groaned as she adopted a fighting stance. "It can survive its body being destroyed?"
Death leveled its sword, pointing it in turn at each of its attackers- and then promptly turned, and began running toward the door. It was either beating a tactical retreat, given the level of damage its armor had taken, or simply had decided that the five Riders weren't easy enough prey. Yui moved in pursuit. "No you don't, dammit!"
ONE. TWO. THREE. RIDER KICK!
Dropping to the ground, Yui slid along the floor in a straight line, energy gathering around her legs and body as she homed in on the enemy's legs-
And suddenly the skeleton wasn't there anymore. Yui skidded to a halt. "Wha-"
The sword caught her across the midriff, flinging her bodily into a wall and cancelling her transformation, before she could finish her sentence. Gasping for air, she fell to her knees. Dimly, she wondered if the weight Death had shed with its lost armor had allowed it to pick up speed as she feebly raised up a hand, a shadow looming over her with its sword held above its head-
A burst of flame struck the shadow from the side, and it was forced away from her. Yui sucked in air, still hurting. "Shades?"
"Pitiful creature. Your life is now forfeit!"
Yui razed her head, staring at the new arrival. Tall. Blonde. Muscular. Dressed in a leather fighter pilot's jacket and jeans. His belt was the same nondescript silver as her own, but the buckle bulged outward, the top containing a slot and the center being some sort of display case. The newcomer- Blondie, Yui mentally named him- raised a small object into the air. A metal object, which on closer inspection looked like a silver cross formed from blades. "Henshin!" He inserted the object into the belt's slot as he was bathed in a cooling, white light.
Henshin Engage. All System Power Up. Core Weapon, finalized. Blazon feedback maximum. Prepare for next combat. Kamen Rider, go.
The white armor which coated the warrior's body was plated, not unlike Death's, but not nearly so bulky and probably far more comfortable to move in. Rather than a knight's helm, the new fighter's mask seemed to echo the shape of a crowned king, complete with gems set in its crest. Rather than standard eyes, a V-shaped visor glowed with energy as the warrior snapped, a blue cape materializing. In his right hand, he hefted a massive claymore. "You, who defies the rules of this world," he said, pointed the blade at Death, "DISAPPEAR!"
Advent Slash.
With a roar, the knight drew back his blade, and brought it down. The resulting discharge of energy far dwarfed that of Exelion or Ryuusei's final attacks, releasing a column of light which punched a hole straight through one of Jump!'s walls. Death screamed as his body was reduced to ash, the blue flames which had covered his skull being put out instantly. Satisfied, the warrior struck his belt once more, his armor vanishing. "Farewell, subjects," he said, dismissively waving to the assembled Riders before rushing away.
In the distance, the neigh of a horse could be heard.
"The... hell?" Yui groaned, managing to pick herself up from where Death's attack had thrown her. "Who was that-"
She caught sight of her brace again, shaking it. "The hell?"
The total- even after the monster had been completely annihilated- hadn't increased at all. "The hell is this? Is it still alive?"
